I want to use a Trampa BMS in a project with (at least) four VESCs. I realize it uses CAN, so every VESC should be able to get the BMS status. Is there some coordination for limiting usage, though? If two of the VESCs aren't drawing much current, I want the other two to have the full current available. I don't want to simply limit each one to using one fourth the available current.
There is no limitation of current by the BMS itself as it has no Discharge Mosfets. The battery current settings in each VESC decide the amount of current each VESC draws.

Yes, that's why I'm asking. If the BMS handled it, there wouldn't be an issue (other than having it cut off).
I'm really questioning if VESCs have built-in cooperation on power usage, regardless of BMS. But I expect that multi-motor VESC BMS users have already grappled with this.
I half expect that I'm going to write a custom app for it, but I don't want to re-invent it.
